Sports otitis media
(I) Cause
When swimming, water enters the ear canal to make the tympanic membrane soft. At this time, if a cotton swab or finger is used to go blindly in the ear canal, the tympanic membrane is easily damaged, and bacteria invade the middle ear. If the tympanic membrane breaks through and continues to swim underwater, bacteria will directly invade the middle ear from the external auditory canal, causing inflammation. Due to water in swimming, bacteria can cause inflammation from the eustachian tube into the middle ear.
(b) Signs
When the skin infection of the ear canal is swollen, pressing the nerve endings under the skin directly can cause severe pain in the ear. Especially when chewing, yawning, or oppressing the tragus, the pain will increase and the hearing loss may occur, sometimes causing fever and headaches. When the tympanic membrane ruptures, yellow pus flows from the external auditory canal, and local pain and systemic symptoms can be greatly reduced. Acute inflammation may be converted to chronic otitis media if the treatment is not timely or thorough.
(III) Processing
Ask your doctor for treatment. Generally can rest in bed, adapt to drink plenty of water, oral pain tablets, while penicillin injection. If the tympanic membrane is broken, use 30 % hydrogen peroxide to wash it, add a disinfectant (such as glutamic acid, etc.), and then use a sterile tampon to remove the external auditory canal. In addition, it can be used as a hot compress and infrared radiation in the mastoid part, and it can also accelerate the blood circulation of the affected part and promote swelling and inflammation.
(d) Prevention
Prevention Do not swim in unclean rivers and lakes. When swimming, ear plugs can be used to block the outer ear, crossing the mouth, preventing water from entering the ear canal or dripping 1-2% phenol glycerine or coating with vaseline in the external auditory canal before swimming to reduce the chance of water staying in the ear canal. After swimming if the ear water, can be used to the side of the head to the water side of the ear, with the same leg to jump in place, the water is flowing out, and then carefully wipe the ear canal with a cotton swab, or drop a few drops in the ear Boric acid alcohol, avoid earing. When you have a cold, upper respiratory tract infection, or otitis media, do not swim for the time being.
